(WINDOW-LOCK.

SPECIFICATION forming part Of Letters Patent N0. 702,198, dated June 10, 1902.

Application filed March 6, 1902. Serial No. 96,904. (No modehl r the accompanying drawings.

This invention relates to certain new and useful improvements in window-locks, and relates more particularly to window-sash looks.

The present invention has for its object the provision of novel means whereby a window sash may be securely locked at any desired height; furthermore, to providenovel means that will engage in the side of the windowframe and retain the window-sash in a locked position at any desired, point, and also provide novel means whereby the locking mechanism may be easily unlocked, allowing the window to be raised or lowered.

My invention still further contemplates to provide a device of the abovedescribed class that will be extremely simple in construction, strong, durable, comparatively inexpensive to manufacture, and highly efficient in its use.

With the above and other objects in view the invention consists inthe novel combination and arrangement of parts to be hereinafter more fully described, and specifically pointed out in the claims.

In describing the invention in detail reference is bad to the accompanying drawings, forming a part of this specification,and Wherein like numerals of reference indicate like parts throughout the several views,in which- Figure 1 is a front View of the upper portion of a window frame and sash with my improvements attached. thereto. Fig. 2 is an enlarged vertical sectional view of the shaft carrying the square end and pinion to operate the locking mechanism. Fig. 3 is an enlarged vertical sectional view of the keeper, showing secured therein the lockingbolt. Fig. 4. is an enlarged-fragmentary view of the rack-bars carried at the end of the operatinglevers. a

In the drawings the referencenumeral 1 represents the window-frame, in which is socured on each side rackJoars 2.

3 represents the window-sash, carrying operating-rods 4 and 5. The operating rod 4 carries an extension 6, forming the rack-bar 7, which engages the upper periphery of the pinion 8, the latter being journaled in the casing 9 and secured to the operating-shaft 10, carrying the square end 11. The other operating-rod 5 also carries a rack-bar 12, which meshes in the lower portion of the pinion 8. These operating-rods 4 and 5 are pivotally connected at 1415 to rods 16 and 17, these rods 16 and 17 being fulcrumed at 18 to the window-sash, and their lower endsextend through the openings 19 of the lockcase 20, the latter being rigidly secured to the window-sash. The ends of the rods 16 and 17 are connected at 21 to the locking-bolt 2, which is slidably secured in the lock-case 20, said locking-bolts being adapted to be operated simultaneouslyinwardlyor outwardly. These locking-bolts engage in the rack-bars and serve to securely lock the window-sash in position. The said operating-shaft 10 carries a spiral spring 10, which is secured to the casing 9 and to the operating-shaft 10. Thus when the shaft is operated or turned in either direction it will Wind the spring, and the shaft upon being released will actuate the cog 8 through the. medium of the spring to cause the locking-bolt 22 through its connection to be seated in or returned to engagement with the racks 2. V

opening formed therein is operated to engage the square 11 of the shaft 10, and by turning the said shaft the operating-rods 4 and 5 will be simultaneously operated inwardly or outwardly as the shaft is turned in one direction or the other. These operating-rods carry with them the rods 16 and 17 and will turn upon their fulcrum 18, thereby operating the locking-bolts inwardly or outwardly, as 'will be readily understood.

The many advantages obtained by the use of my improved device will be readily apparent from the foregoing description, taken in connection with the accompanying drawings. It will be noted that various changes may be made in the details of construction without departing from the general spirit of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a sash-look, the combination of a window frame and sash, rack-bars rigidly secured in said win dow-frame, operating-rods carrying rack-bars secured upon said window-sash, a pinion for simultaneously operating said operating-rods in opposite directions, rods pivoted to said operating-rods fulcrumed near their center, and locking-bolts secured to said last-named rods engaging said rack-bars, substantially as described.

2. In a sash-lock, the combination of a window frame and the sash, rack-bars secured in the frame, lock-casings having a locking-bolt slidingly mounted therein carried by the sash, a casing carried by the sash and having a shaft carrying a pinion therein, operatingu'ods having rack-bars formed on their one ends engaging said pinion and adapted to be simultaneously actuated thereby, centrally-pivoted rods carried by the sash with their lower ends extending into said lock-casing and engaging said locking-bolt, the upper ends of
